2 Overview 1. The Problems 2. The Solution 3. Visio Shapes 4. VBA Macros 5. Results 6. Caveats 7. Next Steps

3 The Problems Two problems Reduce documentation Common symbols that VUIDs could use Have a document and symbol set that are… Clear enough to present to business-minded people Technical enough to hand over to developers Formal enough to be “automate-able” Easy to maintain

4 Other Solutions Formal UML has been proposed by Mark Stallings of IBM (SpeechTEK, 2006) V-Builder (Nuance: http://www.nuance.com/voiceplatform/) http://www.nuance.com/voiceplatform/ SpeechDraw (http://www.speechvillage.com)http://www.speechvillage.com Others... All are more towards the code end of the spectrum

5 Details, Details… Finding the right level of detail to present

6 A Solution Reduce documentation by allowing the callflow to store more data. Visio template of UML-style shapes which VUIDs can use as a common “language”. Macros for automating common tasks.

7 The Shape Sheet is Daunting

8 Shapes & Their Properties Shapes use Visio’s “Custom Properties” fields Allows for structured data, custom presentation, and automation.

9 The Shapes Grammar State State name Main prompt name & TTS Two reprompts Grammar name Prompt State State Name Prompt name & TTS

10 The Shapes Checkpoint Decision text List of variables Open-ended for further automation

11 Shapes Start/End Off-Page Reference Database Computational State

12

13 The Macros Export_Prompts Puts all prompts in Prompt & Grammar states into Excel IterateOverConnections Exports a computer- readable text representation of the flow List_Of_Grammars Exports the list of grammar names and the states in which they exist

14 Design Assumptions Prompts & Grammars have state names Every grammar state has a main prompt, two reprompts, and the name of the grammar If the main prompt is named “Main”, the reprompts are “MainR1” and “MainR2”. Only the top-level prompt is exposed Formal but flexible. You won’t get an error if something isn’t defined.

15 Results Successfully in use both at Countrywide Home Loans & Genesys Labs Readable by both business & development teams Greatly assisted in document management Prompt lists are generated from the callflow Scripts & recording lists use the prompt list

16 Caveat Aedificator This is a Visio-only solution Macros require Excel There are issues converting between Visio 2002 & 2003 Output of IterateOverConnections is more of an example than something in-use No restrictions (e.g., type-checking, loops, etc.)

17 Where to get it Step 1: Sign up for the VUIDs User Group: http://tech.groups.yahoo.com/group/vuids/ Step 2: Click on “Files” Step 3: Download “VUID Tools Lite.zip”VUID Tools Lite.zip Step 4: Participate!

18 Conclusion & Next Steps Publicly available, Visio-based stencil & macros as a starting point for a common symbol set for VUIDs. The level of “formality” allows for flexibility in design with structure enough for automation. This is an extendable solution, so start extending!
